51 Pegasi b. Visiones de futuro (NASA)

“While there is much debate over which exoplanet discovery is considered the "first," one stands out from the rest.

In 1995, scientists discovered 51 Pegasi b, forever changing the way we see the universe and our place in it. The exoplanet is about half the mass of Jupiter, with a seemingly impossible, star-hugging orbit of only 4.2 Earth days.

Not only was it the first planet confirmed to orbit a sun-like star, it also ushered in a whole new class of planets called Hot Jupiters: hot, massive planets orbiting closer to their stars than Mercury. Today, powerful observatories like NASA's Kepler space telescope will continue the hunt of distant planets”.

51 Pegasi b es el primer exoplaneta, o sea de fuera del sistema solar, descubierto por el hombre. Se detectó gracias al estudio de un espectrógrafo en 1995.

Por lo que sabemos de él, nos interesa saber de su luz. Es como el más allá.
